Dies ist eine sehr coole HTML5-3D-Animation zum Umblättern von Büchern. Der Effekt ist relativ einfach, um das Umblättern von Seiten zu simulieren. Was noch schöner ist, ist, dass beim Umblättern ein realistischer 3D-Effekt entsteht . Der Text und die Bilder im Buch werden auch in 3D angezeigt, was sehr cool ist.
